Part of the reason this one is slower than yours with half as many cylinders is because the displacement is higher. The same amount of air from the vacuum cleaner is passing through a larger number of cylinders than in my one- and two-cylinder engines, which run much faster. See my videos on those and my 2x2 I4 which runs much faster too.

@mel_energy 👍

I posted a walkthrough video a few months after this one about how it works

Exactly. See my other video on this engine where it has a cross-plane crankshaft

I posted a walkthrough of the normal version of this engine in December 2019, they’re pretty similar

You’re right, it is weak at these speeds. I soon realized I could use a 1x6 half stud wide beam as a connecting rod and that’s what I’ve been doing since.

I made a 2-cylinder already and posted a video of it, and check out my video of a 1-cylinder running a 4-speed transmission

@mel_energy MAKE A CAR WITH IT PLEAAAASE

Yes, I started doing that after this video

Have you lubricated it?

@@alexkainua1351 I already made one, it’s one of the early videos posted on my channel

This might have been oiled/lubricated but it’s a flat-plane crank on a two-stroke engine so it doesn’t work great. See the next video I posted where it has a cross-plane crank.

@@Roblox_studio_Dev I posted pictures of the parts in the description and made a walkthrough video

Yup

Good luck! Post a video if it works

Thank you! My original idea was to make one with a few more air lines leading to it and some more cylinders inside so I could control it all from one switch box and didn't have to walk back and forth to flip switches on it (I cut those bits out). Maybe I'll get some more hose and make a video some day. P.S. can we trade jobs?

@@mel_energy My job is to clear the trees, fences etc so they can get into bush to do a job, and tidy it up later. This week we had to take down 8 x 15 mtr pines, drag them 30 mtr down the hill with the tractor and straps, get them to the base of a swamp, so the beast can go in and clear out a big wetland. It's crazy, cause a machine like that needs another huge truck to move all the stuff dug out for future use, and other smaller machines around it, it's amazing to watch. They are all young dudes. Much success for you, congrats on 1 k subs.

@@robloxian7761 I’m sure it would be possible but Lego vacuum engines are normally not very air tight so it might be tricky to get it to run for long with a normal size balloon. But go ahead and run some experiments

I don’t do tutorials for my designs, mostly because I believe that limits the way it can be made if I do a piece-by-piece walkthrough. A few years ago I showed how a small prototype of a one-cylinder version worked, though. But this isn’t a very efficient model.

@@bouchrarouane9034 It’s already lubricated, you can see it through the sidewalls when it starts. And I’ve already learned to use a one-piece connecting rod instead of this one so it doesn’t come apart.
